This is the why from UpTodate: Outpatient therapy is usually the best option for lower risk individuals (eg, patients who are medically stable and are not imminently suicidal) [19,25]. Outpatient therapy requires the involvement of the family and their willingness to stay with the patient indefinitely [2,12,13]. All lethal means of suicide, particularly firearms and medications, should be made unavailable to the patient. The acute crises that precipitated the event must be addressed and attempts made to resolve them. The patient and parents should be warned about the dangerous disinhibiting effects of alcohol and other drugs . Psychiatric follow-up must be secured within 48 hours and the patient and family members should be instructed to return to the emergency department if things are not going well30.

had spoken of suicide to a friend but states that he does not want to hurt himself because of religious beliefs â€œMy family would be hurt, too." he states. He has no history of
medical or psychiatric illness and takes no medications He does not smoke cigarettes or drink alcohol Physical examination shows no abnormalities On mental status
examination, he is cooperative and makes good eye contact In addition to recommending outpatient therapy, which of the following is the most appropriate physician
recommendation to this patient's parents?
o A) â€œDonâ€™t make him go to school until he feels better. He canâ€™t concentrate in his present state of mindâ€
O B) "Let him rest and spend time alone. He needs space to think.â€
o C) "Make sure he does not have access to gunsâ€
o D) "Perhaps you should invite his ex-girlfriend over to cheer him upâ€
0 E) "Pray with him daily. Religion is an important protective factorâ€
Answer is A. I got it right in online nbme. many reasons: out of 530 only 100 remained in the study. this "loss to follow up" creates huge selection bias problem. so differential followup here means that people of different exposures are followed differentially distorting the results.A cohort study is conducted to assess the relationship between oral contraceptive use and risk of breast cancer.

Which of the following features of the study is most likely to affect its validity?
